Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Area of Science:

Dermatology
Cryotherapy
Medical Devices

Background:

Acne vulgaris presents a significant dermatological challenge.
Current acne treatments have limitations and side effects.
Investigating novel therapeutic modalities for acne is crucial.

Purpose of the Study:

To assess the feasibility and efficacy of precision cryotherapy for acne vulgaris.
To evaluate the safety and participant satisfaction with precision cryotherapy.

Main Methods:

A pilot clinical trial involving 20 volunteers.
Targeted precision cryotherapy using a carbon dioxide-based device.
Assessment of outcomes via Investigator Global Assessment (IGA) score, lesion count, erythema index (EI), global evaluation, and participant satisfaction.

Main Results:

A significant 90.25% reduction in acne lesion count by week 4.
Clinical improvement shown by reduced IGA scores (p < 0.001).
High participant satisfaction (6.75 ± 0.79) and no reported adverse events.

Conclusions:

Precision cryotherapy is an effective, safe, and satisfactory treatment for acne vulgaris.
It shows potential as an alternative therapeutic option, particularly for patients with limited choices.
Further research is warranted to confirm findings and elucidate mechanisms of action.
